Abstract
In mobile devices, the battery-based power is a precious resource. To maximize the network lifetime becomes a challenge issue in MANETs. We found that transmission collision is a problem which affects the energy saving much. If we can reduce the numbers of the transmission collision, we save more power. In this paper, we propose a new mechanism to address this problem and hence prolong network lifetime. Our approach, based on Relative Neighborhood Graph (RNG), adjusts the transmission range according to the degree of the node which is only based on local information. We also suggest appropriate transmission power ranges to some routing protocols such as AODV, DSR and BELLMAN-FORD. Simulation results show that a great improvement of the energy saving for those routing protocolss when comparing with the performance of those protocols without applying our mechanism. © 2005 IEEE.
